TCI tooth tricone bits

Product explanation:
Detailed Description of the four types Tri-cone Rock drilling bits

1. Metal-face sealed bearing TCI Bit
Cutting Structure The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Gauge Structure Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure 1. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
2. The advanced metal seal package will improve the reliability and durability of bearing seal.
Main Type Available Size: 6", 6 1/2", 7 1/2", 8 1/2", 9 1/2", 9 5/8", 9 7/8", 12 1/4", 17 1/2", etc.
IADC Code: 4-- Series, 5-- Series, 6-- Series, etc.

2. Elastomer sealed bearing TCI Bit
Cutting Structure The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit. The tricone bit field is composed of a shallow sequence of sediments of fluvial origin, in which sandstone channels contain heavy oil with gravity ranging from 11 to 13°
Gauge Structure Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure 1. Abrasion resistance and seizure resistance of the bearing are improved.
2. Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.
Main Type Available Size: 5 7/8", 6", 6 1/2", 7 1/2", 7 7/8", 8 1/2", 9 1/2", 9 5/8", 9 7/8", 12 1/4", 14 3/4", 17 1/2", etc.
IADC Code: 4-- Series, 5-- Series, 6-- Series, etc.

3. Air Cooling Roller Bearing TCI Bit
Cutting Structure The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques.
Gauge Structure Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.
Bearing Structure Air cooling roller bearing package. Balls lock the conewhich reduces the probability of cone-dropping to minimum. The HH tricone bit Series reduces sound to a maximum of 60 decibels at the location limit, compared to conventional rigs where sound averages up to 120 decibels.
Main Type Available Size: 8 1/2", 9 1/2", 9 5/8", 9 7/8", 10 5/8", 12 1/4", etc.
IADC Code: 5-- Series, 6-- Series, 7-- Series

4. Non-Sealed Roller Bearing TCI Bit
Cutting Structure Dubowitz also recommended that Washington vigorously enforce Iran sanctions, imposing heavy penalties on tricone bit violators. His full statement is available.
Bearing Structure Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cdropping to minimum.
Main Type Available The president is issuing tricone bit edicts, Congressional representatives are falling over themselves vying for camera time to get their comments out there, and everyone is demanding answers that will not exist until a thorough drill pipe investigation by experienced oilfield professionals has been conducted
